See the full documentation at https://yihui.org/en/2018/11/md-js-tricks/.

alt-title.js

Add the title attribute to <img> if the attribute does not exist. The value of the attribute is taken from the alt attribute. It modifies

<img src="foo.png" alt="an image" />

to

<img src="foo.png" alt="an image" title="an image" />

Then the image will have a tooltip on mouseover.

center-img.js

Center <img>, <video>, and <object> on a page if they are the only child of their parent element.

code-lang.js

Add the language- prefix to the class name of <code> inside <pre> when appropriate, so that syntax highlighters such as prism.js can work.

copy-button.js

Add a copy button to any element (by default, <pre> code blocks) on a page. See this post for details.

dl-fieldset.js

Convert definition lists <dl> to <fieldset>. See more information in this post.

docco-classic.js

Find code blocks on a page and put them in the right column. Other elements will be placed in the left column.

external-link.js

If a link of <a> does not start with http:// or https://, add the attribute target="_blank" to <a> so it opens in a new tab/window.

faq.js

Turn an ordered list on an HTML page into a collapsible FAQ list. Click on any question to toggle the visibility of its answer. Or click on the button at the top-right to expand or collapse all answers. Each FAQ item has an anchor (shown as the # symbol at the end on mouseover) that provides the link to the specific question.

Note that you will need to load faq.css accordingly. See a more detailed introduction here.

fix-footnote.js

Add [ ] to footnote numbers and move the return symbols in footnotes.

fix-toc.js

Fix the table of contents generated by lower versions of Hugo.

fold-details.js

Move elements into <details> so that they can be folded. By default, code blocks (<pre>) are folded. Other elements can also be folded via custom options. See this post for more information.

fold-output.js

Click on a code block of the class language-* to toggle the visibility of its siblings on the page before the next language-* block. Click while holding the Alt key to toggle siblings of all language-* blocks on the page.

fullwidth.js

Find <pre>, <table>, and TOC (with ID TableOfContents) elements and add the fullwidth class to them if they are too wide, so they can be styled differently (e.g., full bleed).

fuse-search.js

Perform client-side site searching via Fuse.js. See this post for an application to Hugo sites.

hash-notes.js

Convert HTML comments of the form <!--# comments --> to <span class="hash-note">comments</span>. If such comments are found, the document body will gain classes has-notes and hide-notes. You can use CSS to style the notes or hide/show them as you wish.

heading-anchor.js

Add anchor links to all section headings (e.g., <h2>) that have nonempty id attributes.

key-buttons.js

Find keyboard keys in <code></code> and convert the tag to <kbd></kbd>, e.g., convert <code>Ctrl + C</code> to <kbd>Ctrl</kbd> + <kbd>C</kbd>. With key-buttons.css, the keys will be styled as boxes with shadows like buttons. You can learn more details in this post.

load-highlight.js

Disable highlight.js's auto language detection, and then apply highlighting. This requires highlight.js to be loaded in advance.

math-code.js

Write LaTeX math expressions ($\alpha$) in <code></code> in HTML or a pair of backticks in Markdown (which will be rendered to <code> in HTML), and this script will remove the <code> tag, so that MathJax can recognize the math expressions (by default, MathJax ignores math in <code>).

no-highlight.js

Add the nohighlight class to <code> in <pre> when it does not have a class, so that highlight.js will not try to syntax highlight the code in it.

number-captions.js

Number figure and table captions.

number-sections.js

Find all section headings (h1 - h6) and number them.

ol-id.js

Add IDs of the form li-N to items in ordered lists, where N is the index of a list item. This makes it possible to reference or locate a specific item on a page by a hash in the URL. If you hold Alt and click on an item, you will get the URL with the hash in the address bar of your browser.

render-katex.js

Simply run renderMathInElement(document.body) to render math expression using KaTeX's auto-render extension.

right-quote.js

Right-align a <blockquote> footer if the footer is a <p> that starts with the em-dash.

snap.js

Create HTML slides using the CSS Scroll Snap technique.

tabsets.js

Create tabsets from section headings and their content. See this post for documentation.

toc.js

Automatically build a table of contents (TOC) from all section headings.

toc-highlight.js

Add a class active to the TOC item (<a>) corresponding to the section heading that is currently being scrolled into view.
